The reliability of Alva's logic test was estimated using a sample of 250 people (67.6% male, 30.8% female, 1.6% unknown) completing the test on our platform. The observed internal consistency (Cronbach’s alpha) was 0.91, which is considered Excellent by the European Federation of Psychologists' Associations (EFPA).
